kennytm 23689cc8e9 Rollup merge of #49496 - glandium:master, r=sfackler ...

Add more vec![... ; n] optimizations

vec![0; n], via implementations of SpecFromElem, has an optimization that uses with_capacity_zeroed instead of with_capacity, which will use calloc instead of malloc, and avoid an extra memset.

This PR adds the same optimization for ptr::null, ptr::null_mut, and None, when their in-memory representation is zeroes.
